All I heard was a loud bang in my head, and I was knocked unconscious.

When I gradually woke up, I only felt a headache in my back, and my whole body hurt, but if it wasn't for Bai Yan protecting me with his true qi at the critical moment, I am afraid that my spine would be broken by now.

I just struggled to sit up, and I saw Bai Yan sitting on the strange stone grinding the spirit grass, the red powder fell lightly on the paper, it was really rare to see him do things so seriously, if I hadn't met Childe first, I'm afraid I can't guarantee that I won't like him now......

"Why do you want to grind this spirit grass into powder?" I asked in a remote voice.

"There are too many villagers, and one plant is not enough, so I have to grind it into powder and condense it into a silver needle." He only said that, but he never let go of what he was doing.

"I don't understand, if you want to grind, why don't you use your true qi to disperse it directly, and prefer to use this most troublesome method?" I got up and approached him, and he asked again.

"Because only the medicinal materials developed by one's own hands can know their temperature, shape, strength, and quality, so that they can consider the medicine, understand?" He only spoke slowly.

I was naturally a second monk about this, and I didn't know what to do, so I just sat quietly on the bluestone on the side and watched him finally grind this spiritual grass into powder, and picked up a lot of wet firewood on the ground not far away, and luckily dried it to regenerate a fire, I just wondered, "It's not cold in this deep cave, why make a fire again?"

He was too busy to stop for a while, so he only took the time to throw a smile at me and said, "This fire is not used for heating, but for refining needles." ”

He only sprinkled the powder in the fire, and took out the needle bag, and put all the silver needles in it in the fire, and after a long time, the sparks gradually went out, and the silver needles were revealed again, and they were all burned red and hot, and it was done.

He put the needles back into the needle bag one by one, and then said with peace of mind, "It's finally successful!" ”

I jumped up and down happily when I saw this, "Great, those villagers are finally saved!" ”

My afterglow accidentally swept the scars on his hands, and he, only hid these in his sleeves and didn't want people to find out, I only glared at him, and forcefully raised his hand to see, "Your hand is injured, it must have just been made by grinding that spirit grass." ”

He was fine, he just shook his hand, and looked indifferent, "This little injury, it's okay." ”

I was still worried about his injury, but he only pulled me and flew up on the slippery walls of the cave as light as a swallow.
